3: THE PROGRAMS & PARAMETERS PARAMETERS PROVIDED FOR ALL PROGRAMS LEVEL PARAMETERS (Accessed via LEVEL key) Effect/Direct Signal Balance (BALANCE): 0 - 100% This parameter adjusts the balance between the direct sound and effect signals. At 100% only the effect sound is delivered from the SPX900 outputs, while at 0% only the direct sound is output. At a setting of 50%, the direct and effect sounds are output in approximately equal proportions. Effect Output Level (OUT LVL): 0 - 200% This parameter sets the overall output level of the effect program. This is particularly handy for matching levels between different effects. DUAL EFFECT PROGRAM (PROGRAMS 48 - 50) LEVEL PARAMETERS The level parameters available for the dual effect programs (programs 48 - 50) are the same as those for the other programs, except that separate parameters are provided for the left and right channels. BALANCE 1 = Effect 1 Balance BALANCE 2 = Effect 2 Balance OUT LVL 1 = Effect 1 Output Level OUT LVL 2 = Effect 2 Output Level EQ PARAMETERS (Accessed via EQ key) When the EQ key is pressed, you are presented with three choices: "OFF" (the default setting), "EQ" (2-band parametric equalizer mode), or "D.FLT" (Dynamic Filter mode). Use the parameter Q and 9 keys to select the desired mode of operation. The EQ mode'provides 2-band parametric equalization, while the Dynamic Filter mode provides a filter which can be automatically swept across a specified frequency range by the SPX900's internal low frequency oscillator. • PARAMETERS AVAILABLE IN THE "EQ" MODE Low EQ Peaking or Shelving Response (LOW EQ.): PEAK, SHLV High EQ Peaking or Shelving Response (HIGH EQ): PEAK, SHLV These parameters determine whether the corresponding band has a peaking or shelving filter response. PEAK SHLV INPUT SIGNAL LEVEL X"\ FRQ FRQ Low EQ Frequency (LOW FRQ): 32 Hz - 2.2 kHz High EQ Frequency (HIGH FRQ): 500 Hz - 16 kHz These parameters determine the center frequency for equalization in the corresponding band. In the shelving mode, these parameters represent the turn over frequency rather than the center frequencies. Low EQ Gain (LOW GAIN): -15 - +15 dB High EQ Gain (HIGH GAIN): -15 - +15 dB These parameters determine the amount of boost or cut applied to the corresponding EQ band. INPUT SIGNAL LEVEL GAIN (+) GAIN (-) Low EQ Bandwidth (LOW Q): 0.1 - 5.0 (PEAK mode only) High EQ Bandwidth (HI Q): 0.1 - 5.0 (PEAK mode only) These parameters determine the bandwidth of the corresponding EQ band. A setting of 5.0 produces the narrowest bandwidth (sharpest response), and the minimum setting of 0.1 produces the widest bandwidth (broadest response). Note that the "Q" parameters for the low and high bands only function when the corresponding band is set to the PEAK mode. INPUT SIGNAL LEVEL Q=LOW Q=HIGH 9
